OK, folks, can someone help me on this?
I keep receiving an error from a camera statement that is
stright from the docs.

I get Parse Error: No matching } in 'camera', look_at found instead
I have looked through the ng's to fine a post that might talk about
this, but didn't find anything. I thought it might go away if I
rebooted, but no luck. Whats up?

Here is the bit of code that gives this error and some quotes
from the docs.

#declare Here=<0,0,0>;
  #declare Long_Lens =
   camera {
    location -z*100
    angle 3
   }
  #declare Short_Lens =
   camera {
    location -z*50
    angle 15
   }
  camera {
   Long_Lens  // edit this line to change lenses
   look_at Here
  }

/*
CAMERA:
     camera{ [CAMERA_ITEMS...] }
CAMERA_ITEM:
     CAMERA_TYPE | CAMERA_VECTOR | CAMERA_MODIFIER |
     CAMERA_IDENTIFIER
CAMERA_TYPE:
     perspective | orthographic | fisheye | ultra_wide_angle |
     omnimax | panoramic | cylinder CylinderType | spherical
CAMERA_VECTOR:
     location <Location> | right <Right> | up <Up> |
     direction <Direction> | sky <Sky>
CAMERA_MODIFIER:
     angle HORIZONTAL [VERTICAL] | look_at <Look_At> |
     blur_samples Num_of_Samples | aperture Size |
     focal_point <Point> | confidence Blur_Confidence |
     variance Blur_Variance | NORMAL | TRANSFORMATION

Camera identifiers may be declared to make scene files more
readable and to parameterize scenes so that changing a single
declaration changes many values. You may declare several camera
identifiers if you wish. This makes it easy to quickly change cameras.
An identifier is declared as follows.

CAMERA_DECLARATION:
     #declare IDENTIFIER = CAMERA |
     #local IDENTIFIER = CAMERA

Where IDENTIFIER is the name of the identifier up to 40 characters long
and CAMERA is any valid camera statement. See "#declare vs. #local" for
information on identifier scope. Here is an example...

  #declare Long_Lens =
   camera {
    location -z*100
    angle 3
   }
  #declare Short_Lens =
   camera {
    location -z*50
    angle 15
   }
  camera {
   Long_Lens  // edit this line to change lenses
   look_at Here
  }
